If \( \mathrm{M} \) and \( \mathrm{N} \) are any two events, then which one of the following represents the probability of the occurance of exactly one of them?
(a) \( P(M)+P(N)+2 P(M \cap N) \)
(b) \( P(M)+P(N)-P(M \cap N) \)
(c) \( P(\bar{M})+P(\bar{N})+2 P(\bar{M} \cap \bar{N}) \)
(d) \( P(M \cap \bar{N})+P(\bar{M} \cap N) \)
